The IDF has confirmed that the IDF soldier who was critically injured during an operation in the West Bank on Thursday has succumbed to his wounds.

IDF Sergeant Ronen Lubarsky, 20, from Rechovot was a combat soldier in the elite Duvdevan unit. According to the preliminary IDF investigation, Lubarsky was injured when a Palestinian threw a large marble slab from the third floor of a building. He was taken to the intensive care unit at the Hadassah Medical Center in Ein Karem, Jerusalem for treatment. Two days later, he was pronounced dead from his wounds.

Lubarsky was promoted posthumously to the rank of Staff Sergeant, and will be buried at the Mt. Herzl military cemetery in Jerusalem early Sunday morning.

Israeli Prime Minister Benjamin Netanyahu wrote on his Facebook page that he “expresses deep sorrow” over Lubarsky’s death, and promised that “the security forces will reach the terrorist and the State of Israel will bring him to justice.” Meanwhile, the hunt for the terrorist is still ongoing.

Israeli President Reuven Rivlin, who had met with Lubarsky’s family while he was still being treated in the hospital, said: “I also wish to bolster the wonderful fighters and commanders in this difficult hour.” They, he said, are “the best of our boys” who enable Israelis to enjoy safety and security in their daily lives. “We feel the pain of the family and of the unit and we embrace them in our hearts.”

On Thursday night, Lubarsky’s unit arrived at the al-Am’ari refugee camp near Ramallah in the West Bank to arrest suspected terrorists. There, the soldiers were met by a crowd of Palestinians, including gunmen, who approached the moving vehicle, hurling stones and explosives at it.
